Above foregoing description similar in the other parts of the structure of the network print system of not describing 1000 and first exemplary embodiment of the present invention.
Following processing shown in the sequence chart of this exemplary embodiment execution Figure 14.Processing and the processing shown in Figure 10 among the step S1001 to S1012 are similar.
In step S1012, back-end processing unit 402 sends to table stores service 403 with operation and service information acquisition request.More particularly, back-end processing unit 402 acquisition request service quality statistical informations and job information and task information on services.This is interpreted as, and back-end processing unit 402 obtains from service quality statistical form 1300 corresponding to the statistical information of the ID of task service (carrying out count area 1304 and error count field 1305).
Carry out count area 1304 expression task executions number of times.The frequency of failure that 1305 expressions of error count field are executed the task.Job information and task information on services are as mentioned above.
In step S1401, table stores service 403 as to the replying of step S1012, returns to back-end processing unit 402 with job information, information on services and service statistic of attribute information.
After getting access to the service quality statistical information, back-end processing unit 402 determines whether accessed statistic of attribute information satisfies predetermined reference value.
Figure 15 is that described logic is used for determining based on the service quality statistical information whether the service that will call satisfies predetermined quality by the flow chart of the logic of back-end processing unit 402 execution.
With reference to Figure 15, in step S1500, back-end processing unit 402 detects the type of service.In addition, back-end processing unit 402 determines that the service that will call is the service of OUT type task.
Detect COS in the following manner.More particularly, back-end processing unit 402 obtains request receiving element 1206 to attribute and sends request.Attribute obtains to read COS and send in the request receiving element 1206 dependency information memory cells 1207 and replys.
If as definite result of COS, determine that COS is INPUT service or PIPE service, then handles and proceeds to step S1501." predetermined reference value " is meant the mortality of the frequency of failure of expression execution operation with respect to the ratio of total degree.
Back-end processing unit 402 calculates mortality in step S1501.More particularly, back-end processing unit 402 calculates mortality by using following formula:
Mortality=error count (1305)/execution counting (1304) * 100
In step S1502, back-end processing unit 402 determines that whether mortality is less than predetermined reference value.Be under 20% the situation, to satisfy condition in fiducial value (threshold value) if mortality less than 20%, is then thought in step S1503.On the other hand, if determine that in step S1502 mortality is 20% or bigger, then thinks not satisfy condition in step S1504.
On the other hand, in step S1500,, then handle and proceeding to step S1505 if the type of the definite service that will call is the service of OUT type task.In step S1505, back-end processing unit 402 detects the developer of the service that will call.In order to detect developer of services, back-end processing unit 402 obtains request receiving element 1206 input request to attribute, and attribute obtains and reads developer ID in the request receiving element 1206 dependency information memory cells 1207 and reading information is sent as replying.
In step S1506, back-end processing unit 402 determines based on detected developer ID whether the reliability of manufacturer is high.According to as the determining among the execution in step S1506 that get off.More particularly, at first, back-end processing unit 402 calculates by the sum of sum of the error count (1305) of all services of developer's exploitation (promptly wrong sum) and execution counting 1304 (promptly total number of times of carrying out).
Then, back-end processing unit 402 calculates total mortality by using following formula:
Total mortality=total frequency of failure/always carry out number of times * 100
In step S1506, whether back-end processing unit 402 is determined by using total mortality that above-mentioned formula calculates less than predetermined reference value.In addition, based on the result who determines, back-end processing unit 402 determines whether the reliability of manufacturer is high.
For example, when fiducial value being set and being 20%, if mortality less than 20%, then determine to satisfy condition in back-end processing unit 402 in step S1506.On the other hand, if mortality is 20% or bigger, then determine not satisfy condition in back-end processing unit 402.
Determine base condition ("No" among the step S1506) if determine not satisfy, then in step S1507, back-end processing unit 402 determines whether service is verified.If the service of determining is verified ("Yes" among the step S1507), then handle and proceed to step S1508, in step S1508, the quality of predeterminated level has been determined to reach in back-end processing unit 402.On the other hand, if the service of determining is not verified ("No" among the step S1507) as yet, then handle proceeding to step S1509, in step S1509, predetermined quality is determined not reach in back-end processing unit 402.
If satisfy above-mentioned definite base condition, then carry out the processing among the step S1014 to S1019 in the sequence chart shown in Figure 10.On the other hand, determine base condition if do not satisfy, the job information of then carrying out among the step S1402 in the sequence chart shown in Figure 14 is upgraded processing.
More particularly, by upgrading job information and the value of the mode field 706 that comprises in the schedule work 700 is changed into " Failure " in step S1402, control is carried out in back-end processing unit 402, fails clearly to represent operation.In other words, think that operation fails.
